2 Claims.

This; invention relates to an improved assembly of an auxiliary window frame and sash frames fuor panes of transparent material or screen material to be used'veither as astorm window or as a window- Screen and in which the sashes may be easily Slidably mounted upon and removed from their auxiliary frame. Y

To avoid cireumlocution hereinafter, the term storm Window is intended to include both a storm window; and a window screen construction, and the term sash means a frame having either a transparent pane orscreen material therein.

It iS a prime object of the present invention to provide an improved multi-sash assembly which may be easily installed within the avail-v able outer margin-of a standard window frame to provide a completely sealed' storni window or a window screen; Y

Another object of the invention is to provide an improved, simple,l rug-ged, economical and weatherproof construction.

Another object is to provide a storm window or screen of the kind described with improved means for guiding the movement of the sashes.

Another object is to provide in such an assembly novel means to hold the Sashes in adjusted position and tov preventing rattling.

Another object is to provide a storm window in which the -sashes lcannot becomev locked in place either by paint seals between the-sash and window frame or by swelling window frame.

Referring to the drawings in detail, an ordinary window frame I of wood is shown supporting conventional vertically sliding upper and lower glass window sashes 2 and 3, respectively, between the usual side Stiles Il. As usual, the frame I is provided along each upright stile with a parting Strip 5 and outer and inner window stops 6 and l, respectively, which collectively form guides for the vertical sliding sashes. The frame has the usual sill B and header 9, the outer portion of the sill having a sloping surface I0.

The above described structure is conventional and forms no part of the invention except as the associative environment for the improved storm window assembly.

The invention resides lin providing a storm window or screen assembly to be positioned in the frame I outwardly of the sashes 2 and 3. This assembly comprises a wooden .auxiliary window frame including side Stiles II connected at the top by a header I2. The bottom ends of the Stiles rest on the sill 8 and said Stiles are secured to the frame I by screws I3. A portion of the header I2 lits underneath the header il of the main frame I and the remainder of the header I2 extends exteriorly of the header Si and is thickened as indicated at I4. The side Stiles II are provided with opposed outer and inner .groovesv I5 and I6, respectively, extending substantially the length of the Stiles.' Secured to the underside of the thickened portion I4 of the header I2 is a channel-shaped member or plate I'I opening downwardly, and fastened ,to the straight surface portion of the sill' of frame I is a metal plate I8. The outer end of plate vI8 extends over the sloping surface ID of the Sill and is bent to form a channel portion I9 opening upwardly- An upper storm sash 20 and a lower storm sash 2i are slidably supported upon the auxiliary frame and are of lesser width than said frame. Each storm sash consists of an upper rail 22 and a lower rail 23 connected by side rails 2li, said rails being preferably formed of wood. The top rail 22 of each storm sash is covered by a vSubstantially channel-.shaped metal plate 25 which is secured to its rear surface by screws 26. Plate on the top rail of the lower sash 2| is spaced slightly from the outer surface of said top rail providing a channel 21 between the top rail and plate 25 as seen in Figure 3.

Secured to the rear surface of each side rail 24 of each storm sash by screws 28 is a metal plate 29 having a flange portion 36 on one side edge .thereof extending perpendicularly to the plane of the sash along the outer side surface of said side rail but spaced therefrom to provide a channel 3| between the flange and side rail. The flange 30 is cut away at its top end to for-m a slanting upper edge 32 and terminates at a point remote from the bottom end of plate 29 where it is notched to form a lug 33.

Slidably mounted under the channel-shaped plate 25 of each storm sash adjacent each end of its top rail 22 is a latch plate 34 having an upwardly projecting finger piece 35 at one end projecting through an elongated opening 36 adjacent each end of the plate 25 and having a lug 34 at its other end projecting through a slot 31 intersecting the end of the plate.

'Ihe top storm sash 20 has a metal plate 38 secured to the inner surface of its lower rail 23 by screws 39. The bottom end of plate 38 extends below the rail 23 and its bottom edge is bent inwardly and upwardly to form a channel portion 40 opening upwardly as shown in Figure 3.

The inner surface of the bottom rail 23 of lower sash 2| has a plate member 4I secured thereto by screws 42. Plate 4| extends below the bottom rail and is bent outwardly upon itself to form a iin 43, as shown in Figure 3.

To facilitate ready installation and removal of the storm sashes, an elongated sliding shoe member comprising a shoe plate 44 is interposed between each side rail 24 of the storm sashes and the adja-cent stile I I of the auxiliary frame. Plate 44 is shown in detail in Figure 8 and comprises an elongated body substantially L-shaped in cross section, one leg flange 45 of the body being bent inwardly upon itself and away from the other leg flange 46 so that its free edge 41 is disposed adjacent the junction 48 between the two leg portions with the folds of the bent portion separated to provide a channel or groove 49 extending substantially the length of the body and facing perpendicularly to the plane of the sash. Adjacent the bottom of the body the edge 41 of the bent over portion is connected to the leg portion 46 by a bridge portion or crosspiece 50. Below the bridge portion 50 the adjacent leg portions of the plate are notched to provide a clearance between said leg portions as indicated at 5|. One end of the leg portion 45 has an extension which is bent laterally away from the leg portion 4B to form a lug 52 for manipulating said plate.

When in position, the leg portion 46 of the plate 44 is ttingly and slidably mounted in one of the grooves I5 or I6 of the side stiles II and the other leg portion 45 is disposed alongside the inner surface of the adjacent stile with the channel 49 opening inwardly of the window opening as shown in Figure 4. One of said plates 44 is mounted in each of the outer grooves I5 of the Stiles II in the upper half of the window and another of said plates 44 is mounted in each of the inner grooves I 6 in the lower half of the window.

The upper storm sash 20 is disposed between the sliding plates 44 in the outer grooves I5 and is connected thereto vfor movement with said plates. Similarly the lower storm sash 2l is diS- posed between and connected to the Plates 44 in the inner grooves I6 for movement therewith.

The connection between the storm sashes and the plates 44 is effected by rst inserting the pointed lugs 33 on the bottom ends of flanges 36 of plates 29 on the side rails of each sash into the channels 49 of sliding plates 44 at points just above the bridge portions 50 of said plates 44 and then moving the sash inwardly of the channel and downwardly as shown in Figure 9 to bring the lugs 33 downwardly behind the bridge portions 50, said bridge portions serving as pivot points during such movement. Continued swinging movement of the sashes inwardly of the channels 49 will bring the top ends of the sashes into alinement with said plates 44 with the upper surfaces of the channel plates 25 underneath and adjacent the laterally extending lugs 62 on the plates 44. The interlock between the lugs 33 on the bottom ends of the sashes and the bridge portions 50 of the plates 44 prevents lateral or inward displacement of the lower parts of the sashes relative to the window, and outward movement of the latch members 34 on each end of the top rails 22 will bring the lugs 34 of said latch members into interlocking relation with the sides of the lugs 52 away from the bridge on the sliding plates 44 as shown in Figure 10 for preventing lateral or inward displacement of the upper ends of the sashes.

The lower storm sash member 2| is provided with a nger piece 53 on the inner surface of its bottom plate 4| for sliding the sash up and down. When said lower sash is slid upwardly its upper rail which is under the lugs 52 on the plates 44 in the inner grooves I 6 pushes the plates upwardly, and when said sash is slid downwardly the interlock, between the lugs 33 on the bottom ends of plates 29 on said sash and the crosspieces 50 of the sliding plates 44, slides the plates downwardly.

The bottom rail 23 of the upper sash 20 serves as a handle for moving said sash up or down.

When the sashes are in closed position as shown in Figure 3, the channel portion 40 on the lower rail of the upper sash and the channel portion 21 on the top rail of the lower sash are interlocked providing a weatherproof juncture at the meeting edges of the sashes. It will also be observed that the top rail 22 of the upper sash with its channel plate 25 has moved into the channel plate I1 on the header I2 thereby protecting the window from the weather at the top. Furthermore the fin 43 on the bottom rail 4I of the lower sash is in fitting engagement with the channel portion I9 of plate I8 on the sill providing a weatherproof joint at the bottom of the window.

The storm sashes may be locked in closed position as shown in Figure 3.by a pivotal latch member 54 fastened to the top surface of plate 25 on top rail 22 of the lower sash coacting with a slot (not shown) in the plate on the bottom rail 23 of the upper sash.

The sash frames may be held against sliding in the auxiliary frame under gravitational action by any suitable means; but preferably a holding member 55 is fastened on each stile of the auxiliary frame for each of the sash frames to slidably frictionally grip the leg 46 of each shoe plate 44. As shown, each holding member includes a channel seated in each groove I5 and I6 and whose legs 56 are resilient and yieldingly frictionally receive between them the legs 46 of the corresponding shoe, one leg of the channel having a flange 51 lying on the inner face of the corresponding stile of the auxiliary frame and secured by a screw 58.

The storm sashes are removed inwardly of the window. The lower storm sash 2l is first removed by sliding the latch members 34 inwardly ,away from the lugs 52 on the adjacent plates vMl to permit the upper end of the sash to swing inwardly. When it is swung inwardly to the position shown in Figure 9 clear of the upper sash, it is then lifted upwardly and outwardly until the bottom lugs 33 of the sash ride clear of the crosspieces 50 of the plates 44 when the sash can be lifted out of the auxiliary frame. The upper storm sash 20 may then be removed in a similar manner.

The window construction of this invention is of a very simple character and may be cheaply manufactured, and the facility with which its elements may be manipulated enhances its commercial value.

Conveniently, two sets of sash frames may 'be provided, one set having glass and the other set having screening material therein, so that the two sets can be mounted interchangeably in the auxiliary frame, as desired.

Changes in details of construction may be made within the principles of the invention.

What I claim is:

1. In a storm window construction, an auxiliary window frame having stiles with longitudinal grooves therealong, an elongated shoe member slidably mounted in each of said grooves, a sash disposed between said shoe members, each shoe member having a channel facing perpendicularly to the plane of the sash and there being a bridge across the lower end of said channel, each sash having a downwardly extending lug at each side thereof passing into said channel in the corresponding shoe member and separably interlocking with said bridge to connect the lower ends of said shoe members to the lower ends of the sash, a lug on the upper end of each of said shoe members extending inwardly of the window at the upper end of said sash, and sliding latches on the upper end of said sash each to interlock with one of the second-mentioned lugs at the side thereof away from the corresponding bridge for releasably holding the upper ends of the sash against displacement.

2. In a storm window construction as dened in claim 1, said sash having anges on it sideedges seated in said channels of the corresponding shoe members and having said lugs at the lower ends of said flanges, and the slidable mounting of said shoe members in said grooves comprising flanges on said shoe members slidable in the corresponding said grooves in the auxiliary frame.
